At the 2010 Winter NAMM show, ISP Technologies highlighted the recently released HDL 3112, a three-way, small-format, self-powered line array system incorporating three high-frequency drivers with neodymium magnets and 1.75-inch non-metallic diaphragms that deliver a smooth, pleasant high-frequency signature.
A large-format mid-range compression driver covers the upper MF band, eliminating the “cone breakup” of typical cone drivers, enhancing clarity and dynamics. A single 12-inch neodymium driver handles LF, with all three sections driven by proprietary high current DCAT amplification (800 watts RMS total power).
The HDL 3112 is an 8-degree vertical box for long throw applications and is also available in a 15-degree near-field downfill cabinet.
By using a larger woofer and a taller box than typical 2 x 8 boxes, a longer line is formed from an equal number of boxes, resulting in better LF and low mid pattern control.
The HDL 3112 crosses over at 700 Hz from the woofer cones to the mid-range compression driver. The result is more consistent mid-range over wider angles, better pattern control, better projection, and far greater clarity on the voice and instruments.
In addition, the boxes are carefully designed with the aid of ISP’s proprietary LINESIM simulation program to enhance smooth response at all frequencies and listening positions.
